The John Deere 612C StalkMaster is available in 12-row models with 20-in., 22-in., 30-in., 70-cm, and 75-cm row spacing.

The 612C StalkMaster Corn Heads have been redesigned from the ground up to provide the high-capacity and productivity features for which growers are looking. These improved corn heads deliver durability and dependability second to none, plus innovative designs and technology that deliver distinct advantages:

-Higher levels of performance when harvesting standing, down, or leaning crops.

-Takes in less material, increasing separation and throughput, allowing growers to better utilize the higher levels of capacity of the 70 Series STS™ Combines.

-Increased residue management capabilities with more aggressive, longer-lasting knife rolls along with an updated StalkMaster design to fit all stalk-processing needs.

IMPORTANT: The model 612C StalkMaster 30-in. row Corn Head is recommended for use on any model combine equipped with code 1590 (CommandTouch™ multi-speed feederhouse drive system) and code 1730 (80-mm feederhouse lift cylinders).

NOTE: The 9870 STS Combine is recommended to be equipped with intelligent power management (IPM).
